3. Technical Description

This bearing is a double-row self-aligning ball bearing designed to support:

• Radial loads, and
• Small to moderate axial loads in both directions

The self-aligning design (spherical outer ring raceway + two rows of balls) allows it to compensate for:

• Shaft misalignment
• Housing or mounting inaccuracies
• Shaft deflection under load

Compared with the standard version, this bearing has slightly increased radial clearance, which is beneficial when:

• Operating temperatures are higher and internal clearance would otherwise decrease
• Tighter fits are used on shaft and/or housing
• There is a risk of internal preload developing in operation

The polyamide cage helps reduce friction and noise, and provides smooth operation within the specified temperature range.

4. Typical Applications

• Agricultural machinery
• Fans and blowers
• Light-duty transmission and drive units
• Packaging and textile machinery
• General industrial machinery where:
• Misalignment between shaft and housing can occur
• Both radial and moderate axial loads act
• Slightly increased clearance is preferred due to temperature or fit conditions

5. Key Advantages

• Self-aligning capability – compensates for misalignment and shaft deflection
• Double row design – good radial load capacity in compact dimensions
• Slightly increased radial clearance – better behavior under heat and tight mounting fits
• Polyamide cage – quieter, low-friction running
• Open design – flexible lubrication with grease or oil
• Standard tolerance class – easy interchangeability with comparable bearings
